PROCESS OF MANUFACTURING FIRE-PROOF SAF'ES.

SPECIFICATION forming part of Letters Patent No; 405,655, dated June 18,1889.

Appiicaticn fiiai nach 16, 1889.

To all whom, it may concern:

Be it known that I, JACOB BAUM, a citizen of the United States, residingat Cincinnati, in the county of Hamilton and State of Ohio,

have invented a certain new and useful Process of ManufacturingFire-Proof Safes; and I do declare the following to be a full, clear,and exact description of the invention, reference being had to theaccompanying drawro ings, which form a part of this specification. Thisinvention relates to the construction of safes or other similar strongboxes; and my improvement comprises a novel method or process ofYchaiging them with the customary fire-proof filling', which is appliedin the following manner: The safe is made of two principal sections-towit, the outer shell or casing and the inner box, which latter may beintegral with the door-frame, or it may be se- 2o curely attachedthereto, and said casing is filled about half-full with the plast-icfire-proof material. The inner box is then forced into this material,thereby compelling the filling' to pack very tightly within the annularspace between said box and the outer easing, any Asurplus filling beingfree to escape at the joints where the door-frame iits into the front ofsaid casing. The two sections are then united by bolting said frame tothe casing, or 3o the same result may be accomplished by providing theinner box with flanges, lugs, or other projections that embed themselvesin the plastic filling, and thus anchor the inner box so firmly as toprevent its being pulled out after the filling has hardened, ashereinafter more fully described.

In the annexed drawings, Figure l is a vertical section showing theinner box of a safe separated from the outer shell or casing. Fig. .io 2is a similar section showing said casing charged with the fire-prooffilling. Fig. 3 is a section of the safe after the inner box has beeninserted within the shell or casing and secured thereto. Fig. et is asimilar section of a modified construction of the safe.

` Referring to Fig. 2, A represents the bottom, B B the opposite sides,and C the back, of a safe shell or casing, which members A B B C arehere represented as an integral casting, although this construction isnot .essen- Serial No. 303,550. (No model.)

tial lo the carrying out of' my process. The shell has an opening D infront to admit the door-frame E, which latter is fitted up close againstthe flange F of said shell and is secured thereto by screws or rivets G.

H is the inner box, which may be integral with the door-frame, if'desired.

I represents the charge of plastic fire-proof vfilling, composed of anysuitable .material or materials.

In carrying out my process the shell is rst turned over, so as to restupon its back plate C, which act brings the opening D in such a positionas to facilitate the proper charging of said shell. The. plastic fillingI is then 6 5 poured in until. said shell is about half-full, or atleast until there is slightly more filling' within the shell than isabsolutely necessary to charge the annular space of the safe. B0X H isthen inserted within the opening D and 7o is forced down into theplastic filling, thereby gradually displacing the latter and causing itto ascend around the sides of said box. Consequently by the time the boxis completely inserted it is surrounded by the plastic lilling, which ispacked in very tightly and fills every corner and crevice of the safe,the surplus material being forced out at the joints between thedoor-frame and its seat within the shell. The screws G are then run home8o and the filling allowed to harden, which act finishes the productionof the safe, at least as far as the fire-proofing of the structure isconcerned. (See Fig.

It will be noticed that this process enables the ready and completefilling of a safe whose outer shell is a single casting, and it isapparent that the lilling is inserted lwithout perforating said shell orotherwise weakening it;

but the process is equally advantageous when 9o the shell is composed ofa number of members, as seen in Fig. 4, in which illustration the casingor jacket J .is secured to a front frame K and rear frame L, whichlatter is integral with the back plate M, said front frame beingprovided with a flange N, for the doorframe O to .rest against. v

P is the inner box, which is here shown as being attached to the frameO, the rear end of said box being secured to a back plate R. roo

Plate R has flanges or lugs S, projecting some distance beyond the sidesof the box P, so as to embed themselves within the plastic iilling, inorder that the box may be securely anchored in place when the fillingliardens. Therefore these anchoring devices S render it unnecessary touse the screws Gor other visible fastenings.

From the above description it is evident that my process is not limitedto any special construction of safe, but can be used whenever the innerbox is capable of being inserted within a mass of plastic lire-prooffilling.

I claim as my invention` 1. The within-described process of manufacturing safes, which process consists in charging the outer shellwit-h a plasticiire-proof filling, and then forcing the inner box downinto the latter, whereby said filling is gradually displaced and causedto ascend around the sides of said box, so as to enter every corner andcrevice of the safe, the surplus material escaping` at the joint betweenthe doorfraine and its seat within the shell, and said box being securedin place, substantially as herein described. v

2. The within-described process of manufacturing safes, which processconsists in chargingthe outer shell withaplastic fire-proof lling, andthen forcing the inner box down into the latter, whereby said filling isgradually displaced and caused to ascend around the sides of said box,so as to enter every corner and crevice of the safe, the surplusmaterial escaping at the joint between the doorframe and its seatwit-hin the shell, and said box being secured in place by anchoring itin said iilling, substantially as herein described.

In testimony whereof I aliix my signature in presence of two witnesses.

JACOB BAUM.
